SI86SS41BE-AS2

Digital Isolators Overview

The SI86SS41BE-AS2 is a Skyworks automotive-grade digital isolator featuring four unidirectional channels with capacitive coupling. It provides 6.0 kVrms isolation voltage and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V, drawing a typical operating current of 5.2 mA per channel. It exhibits a propagation delay of 8 ns and a common-mode transient immunity of 150 kV/µs. Designed for the -40°C to +125°C temperature range, it is housed in a 16-pin SOIC-WB package.

Digital Isolators Procurement Notes

Verify the specific suffix 'AS2' against official Skyworks documentation to confirm the inclusion of sleep mode functionality and exact pinout configuration. Ensure the component meets AEC-Q100 standards required for your specific automotive application tier. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Digital Isolators Selection Notes

Select this model when high isolation voltage and low power consumption are critical for automotive designs. The integrated sleep mode distinguishes it from standard variants like the SI86SL41BE-AS2. Verify that the 150 kV/µs CMTI rating satisfies the noise environment requirements of your target system interface.

Digital Isolators Part Context

This component belongs to the Si86SS4x family of SPI-compatible digital isolators. It shares the 16-pin SOIC-WB footprint with other Skyworks automotive isolators but offers distinct power-saving features. It complements the broader Si86xx series by providing specialized capabilities for serial protocol isolation in electric vehicle architectures.
